| 英文摘要 | ce3+- and eu2+- doped silica glasses were prepared by impregnation of ce and eu ions, respectively, into porous silica glasses followed by high temperature sintering in a co reducing atmosphere. the characteristic emission band of ce3+ 5d -> 4f transition peaking around 375 nm is observed in the luminescence spectra of ce3+- doped glass under uv and x-ray excitation. its photoluminescence decay is governed by several tens of nanoseconds decay time. for eu2+- doped glass, the eu2+ 5d -> 4f emission band peaking around 430 nm is observed in the luminescence spectra and its photoluminescence decay is governed by a few microseconds decay time. the x-ray excited integral scintillation efficiency of about 82% and 120% of that of the bi4ge3o12(bgo) crystal is obtained, respectively, for the ce3+- and eu2+- doped glasses. scintillation light yield under gamma-ray excitation was also measured and compared with that of the bgo and cef3 crystals. |
